CHARLESTON, W.Va. — Over time, treated oil and gas wastewater is leaving radioactive deposits in the stream beds where it is released, scientists have found.

A team of Duke University researchers found highly elevated levels of radium in the mud where three Pennsylvania treatment plants released wastewater. That's even after the water was treated to greatly reduce its radioactivity, said Avner Vengosh, the professor of geochemistry who led the research team.

"We found that, indeed, there is a large enrichment of radioactive elements in those stream sediments,” Vengosh said. “It's about 600 times the level that we found upstream."

The industry says the brine and other water from oil and gas wells contains some naturally occurring radioactive elements, but only at very low levels. Vengosh and his team have been focusing on the ways these elements become concentrated in stream beds.

Vengosh noted the treated wastewater was from conventional oil and gas wells, not fracking wells - although he said the Duke researchers have found similar issues where fracking wastewater had been released. He added that Pennsylvania stopped the release of treated wastewater from fracking operations some years ago.

He said one troubling issue is how high these concentrations can get - as high as ten times the radioactivity of low level radioactive waste from, say, a hospital or power plant.

"So they are exceeding the level that this site should be, defined as a low radioactive disposal site,” Vengosh said. “Obviously, they are not - it's the middle of a stream in Pennsylvania."

He said most of the nation's oil and gas brine is injected into deep disposal wells, although the geology in Pennsylvania often makes that impossible. Vengosh said treating the wastewater isn't enough.

"I don't think there is a direct human health risk immediately from those sites,” he said. “But there is a chronic contamination of the environment. Even the treatment, it's not sufficient to address this problem."

Oil and gas wastewater is sometimes used to melt the ice on roads. Vengosh said that also may not be safe.

Environmental groups in Arizona say they've faced challenges in advancing environmental protections, and that could now become even harder under a second Trump presidency.

Sandy Bahr, director of the Sierra Club's Grand Canyon Chapter, said during his first presidency, Donald Trump rolled back a number of environmental rules, withdrew from the Paris Agreement and deepened reliance on fossil fuels. She expects Trump to disrupt clean-energy and climate-action progress made under the Biden administration.

"There is a big concern that President-elect Trump will try to reverse full throttle. I don't think he will be able to do that because there will be, at least on some things, enough bipartisan support that he won't be able to just get rid of everything," Bahr explained.

Bahr added while the Inflation Reduction Act will likely be a target for the incoming administration, it is important to remember much of the funds in the legislation have already been allocated to help communities make clean-energy investments.

Bahr said Arizona is already experiencing hotter and longer summers and that could intensify if not addressed, translating to higher energy bills and more deaths each year from the extreme heat.

"The cost of not doing something is much greater than the cost of doing something. Not to mention that clean energy, solar and wind, they're cheaper than fossil fuels. So economically, it just makes sense to do that," she continued.

The transition to clean energy will save the average family up to $7,200 per year in energy costs and another $1,500 per year in health-care costs, according to the Sierra Club.

Bahr says investing in clean energy and climate action goes beyond securing a prosperous future for humans, but encompasses habitat conservation and preservation for species of all kinds.

"One election does not mean that we are not on the right track with what we are asking for. Don't take it as a repudiation of everything that you believe in," she concluded.

As Minnesotans click the "purchase" button when shopping online for the holidays, they're urged to consider two things: toys from overseas suppliers that don't meet safety standards and how e-commerce affects the environment. In its annual toy safety report, the U.S. Public Interest Research Group says loopholes in shipping enforcement allow too many unsafe and illegal products, including those designed for kids, to flood the market.

Teresa Murray, PIRG's consumer watchdog director, said items shipped in bulk that fall below a certain value threshold often avoid scrutiny from U.S. customs officials, and that means for now, shoppers have to be extra vigilant.

"We've also gotten used to how easy it is to shop online, but when people are shopping online, they just need to be super, super careful. Take a few minutes and figure out where that toy is coming from," she said.

Murray added that there are concerns about some toys containing lead or other toxins or having small parts that easily break off, and added that the good news is, there's a bipartisan tone in Washington, D.C., to address the issue. Meanwhile, sustainability experts warn the massive growth in e-commerce leads to more distribution centers in rural areas, increasing trucking distances and exacerbating carbon emissions.

Another concerning trend in the report is the persistent illegal online sales of recalled toys. Murray said brick-and-mortar retailers are more committed to keeping those items out of circulation. Beyond protecting your family and the environment, she suggests replacing digital purchases with in-person shopping might help the economy, because you're fighting back against counterfeit products.

"Frankly, it hurts U.S. companies and U.S. workers when you have these brands that have built a reputation and somebody - you know, it could be domestic, it could be international - and they're making a product that looks just like yours," she explained.

As for e-commerce waste, Minnesota recently adopted a law that incentivizes producers to scale down their use of packaging that often ends up in landfills. A handful of other states have taken similar steps. And online shopping giants like Amazon have highlighted efforts to phase out packaging elements deemed unfriendly to the environment.

A nonprofit group that tracks oil and gas development has created an interactive map to show how close CO2 pipelines in Great Plains states come to environmentally and ecologically sensitive areas.

The map includes Indigenous land that hasn't been included in similar previous projects.

Ted Auch, Midwest program director for the FracTracker Alliance, said it focuses on Indigenous areas but goes further, showing in detail how close proposed CO2 pipelines would come to soybean and ethanol facilities, for example, but also to private land.

He said the interactive map is an improvement over existing ones.

"Which is to say that you could look at it as a static image, but you can't interact with or manipulate the data in terms of, like, scrolling in, scrolling out, finding addresses - you know, that kind of thing," said Auch. "It's available as a PDF or a JPG. So, what we've done is, we've taken that stuff and we've digitized it and we've included it on this map, so that people can actually - spatially and in real time - interact with the data itself."

The Great Plains Action Society says CO2 pipelines pose risks that disproportionately affect Indigenous communities and people of color.

Auch said FracTracker is working on another version that takes a deeper look at the proximity of pipelines to the Winnebago reservation south of Sioux City.

Energy companies say the pipelines are a safe and effective way to capture carbon from industrial processes, and store it underground, reducing greenhouse gas emissions.

Auch said the interactive map will give farmers and other landowners near the proposed pipelines what they need to understand what's happening on their land, leveling the information playing field with corporate interests.

"You have these large, multinational corporations, and then on the other side of the ledger are small, medium-sized frontline or Indigenous groups that either have small budgets or no budgets," said Auch, "and don't have the capacity, the time, or the expertise to develop maps to inform their organizing activism or advocacy."

The Eighth Circuit Court of Appeals in Omaha is making a livestream available as it hears oral arguments today in a case involving Iowa landowners affected by CO2 pipeline proposals, some of whom face seizure of their property by eminent domain if the Summit Carbon Solutions project moves forward.
